Just curious to know, if Nepal needs to chose a second official language, (say like Spanish in USA and French in Canada) which language should be chosen as a second official language?

If you chose the one based on population, it should be Magar language,

If you chose the one based on uniformity of language spoken by the largest majority, it should be Tharu language (because Magar dialects are too versatile)

If you chose one based on ease in availability of literature, historical background, and cultural links it should be Maithali or Nepalbhasa (Newari)

If you chose the one based on uniqueness of nepalese value added with rich cultural ties, it should be Nepalbhasa (Newari)

If you chose the one based on ease of use by the majority of nepalese, it should be Hindi.

Which one would you prefer to chose ?
